A low profile shaft adaptor for coupling an output drive member of an HVAC actuator with an input drive member of a valve. The shaft adaptor may include a clamp for selectively clamping onto the input drive member of the valve, a drive interface configured to form an interference fit with an output drive member of the HVAC actuator, and a bracket configured to mechanically couple the drive interface and the clamp such that rotational movement of the drive interface by way of the interference fit with the output drive member of the HVAC actuator causes corresponding rotational movement of the clamp and thus the input drive member of the valve.

A lightweight construction connection device is provided for a shaft, formed from an end section of a pipe segment, over which the shaft can be slid and having a knurling on the radial outside surface thereof. A support ring is arranged in the interior of the end section of the pipe segment.

A coupling for a roller tube of a window treatment system may include a body and/or one or more compliant members. The body may include a bore through a rotational axis of the coupling. The body may be configured to be received within the roller tube of the window treatment system. The body may define an outer surface. One or more compliant members may extend at an oblique angle from the outer surface of the coupling. The one or more compliant members may be configured to engage a smooth inner surface of the roller tube. The use of compliant members may enable a rigid connection of the coupling to the smooth inner surface of the roller tube surface, without the use of fasteners.

A tool for use with a surgical robotic manipulator that comprises an energy applicator, a tool assembly, and a protective sheath. The energy applicator including a shaft extending along an axis between a proximal end and a distal end. The tool assembly comprises a support structure to support the energy applicator, a connector assembly arranged to engage and releasably lock the energy applicator to the support structure in a locked state, and a drive system coupled to the support structure to rotatably drive the shaft of the energy applicator about the axis. The protective sheath releasably couples to the tool assembly, such that the protective sheath is arranged concentrically about the shaft of the energy applicator between the distal end of the shaft and the connector assembly. The connector assembly has a connector member to facilitate releasable coupling of the protective sheath to the tool assembly.
